IR question answered

A reader writes in asking why shots done in IR seem to extend to much greater depths. The answer has to do with the dust and moisture in the air absorbing more of the shorter wave visible light, and less of the longer wave infrared light. This is also why you see less of the airborne stuff in your IR images.

"The longer waves of the infrared spectrum diffuse less than the shorter visible waves. As a consequence, distant objects will reproduce with more clarity and sharpness. This can be an important factor, especially in landscape and aerial photography," says noted IR photographer and author Cyrill Harnischmacher.
